The Fourth Dimension (2012)

The three
filmmakers have created three unique stories that offer up their vision
of this higher plane of existence, the Fourth Dimension. Each filmmaker
takes his character on a journey that changes the way they see the world
and themselves. And each filmmaker will offer a different perspective
on what the Fourth Dimension is. Kilmer starred in Harmony Korine's short "The Lotus Community Workshop."
He plays a version of himself from an alternate reality, that is a
former actor, turned self-help guru.
